Selecting a Single Channel Pipettor on Amazon.com

Single-channel pipettors are used to fill a receptacle with a predetermined volume of a solution. Sometimes called single-channel pipettes, they are used in laboratories, classrooms, and research facilities to ensure that the correct and consistent volume of liquid is dispensed. While single-channel pipettors dispense liquids into one receptacle at a time, multichannel pipettors dispense liquid into several receptacles at once, and micropipettes dispense liquids in volumes ranging from 2 to 1,000 microliters. A pipette tip is placed on the pipettor to hold the liquid while it is transferred to the receptacle. A manually-operated single-channel pipette has a button that is depressed for aspirating the liquid and pressed again for dispensing. Electronic pipettors can be programmed to aspirate and dispense the liquid with greater precision, ensuring that all the liquid is dispensed.
